I typically rely on local purchase for my bass guitars.
But still, I have purchased more than a few basses through on-line before as well, and they all had been good until my LAST purchase earlier this month.
I won an Ebay auction for a used US made G&L bass on Feb 29th.
But the seller sent me a bass with a crack at the neck pocket and a neck with a split glue joint at the bi-cut, both of which were NOT disclosed at all!!!

I opened a resolution case through Ebay customer support on the day I received the bass on Monday, March 5th because the seller refused to do anything.
So right now, I am waiting to hear from Ebay about the case decision that will be made by the end of this week.
Hopefully, I will get my money back because $700 is a lot of money to spend on a bass with a busted neck!!!
And after this experience, I will probably continue buying on-line, but for purchasing BRAND NEW basses ONLY whether I am buying from MF, GC Web or Ebay.
But I don't think I'll ever buy used basses without personally inspecting one first. Oh no, not after this highly unpleasant experience!
I will continue use Ebay, but for buying small items around $200 MAX.
